I’ve had a 2014 Range Rover Sport v8 supercharged dynamic for almost a year. You might not be as surprised as I am at my combined 23.5 mpg. I was not expecting this. I previously owned an Audi Q7, and I assumed that we would get worse gas mileage with the much larger and more powerful engine in the RRS. My very tiny Audi TTS gets only slightly better mileage. I didn’t buy either because I cared about gas mileage, so it was just a pleasant surprise that a vehicle with over 500 horsepower could be relatively fuel efficient. It is driven mostly in the city too.
